HEEL-PLATE.

Specification of Letters Patent.

Application filed Apri121, 1913.

Serial No. 762,583.

To all whom it may concern:

Be it known that I, ERNEST HUNOLD, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented a new and useful Improvement in Heel-Plates, of which the following is a specification.

My invention has reference to an improvement in heel protectors and more particularly to that form of heel protectors known as heel plates or wearing plates for the heels of boots and shoes.

In the usual construction of heel plates which are stamped or out out of a knife edge bar of metal, the prongs are so placed that all of the prongs cannot be cut out so as to bring all of the pointed ends of the prongs to the knife edge of the bar, to give the same pointed end to each prong, also the shape is usually such that there is an appreciable waste of material in cutting the blanks from the bar.

The object of my invention is to improve the construction of a heel plate stamped out of knife edge bar metal, whereby all of the prongs have the same shape or pointed end, and when bent up into their operative positions a long central and two short end prongs are formed, the shape of the blank being such that when the two short end prongs are bent up at right angles to the plate the pointed ends of the two short prongs converge.

Another object of my invention is to so shape the blank of such a heel plate that the same may be cut out of a knife edge bar with the least possible amount of waste of material.

My invention consists in the peculiar and novel construction of a heel plate stamped out of a knife edge bar of metal, said heel plate having details of construction as will be more fully set forth hereinafter and claimed.

Figure 1. is a bottom view of a shoe showing the heel provided with my improved heel plate. Fig. 2. is a face View of the heel plate blank showing the pointed ends of all the prongs meeting at a common point. Fig. is an edge view of the blank which is cut transversely from a knife edge bar of metal. Fig. 4. is an underside face view of the completed heel plate. Fig. 5. is an edge view of the heel plate. Fig. (3. is

an inner end view of the heel plate, and Fig. 7. is a perspective view of the heel plate looking at the underside of the plate.

In the drawing 8. indicates the bottom of a shoe having a sole 9 and a heel 1.0. provided with my improved heel plate 11. which is stamped first out of knife edge bar metal in a blank form 1.2. as shown in Figs. 2. and 3. The blank 12. has a semi-circular end 13. and rounded sides 14. 14. which converge to form a pointed opposite end 15. from which point the blank is split back approximately two thirds the length of the blank toward the end 13. into three equal portions forming a pointed central and two pointed side arms 16. and 17. 17. respectively. The blank 12. is stamped from a knife edge bar of metal in a position to bring all of the pointed ends of the arms 16 and 17. 17. at the knife edge of the bar. The central arm is now bent at its base at right angles to the plate and the pointed ends of the side arms 17. 17. are bent at right angles approximately one third from their ends.

The completed heel plate is approximately horse-shoe shape and has the semi-circular end 13. the long central pointed prong 1S. and the short pointed end prongs 19. 19. on the ends of the arms 17. 17. at right angles to the plate as shown in Fig. 7. The shape of the blank 12. is such that when the ends of the side arms 17. 17 are bent up to form the short pointed end prongs 19. 1.9. the points of these prongs converge, as shown in Fig. (3. The plate has its maximum thickness at the outer edge or end 13. and gradually diminishes to its minimum thickness at the ends of the arms 17. 17. By this construction all of the prongs have the same tapering pointed ends, the main central prong may be as long as is required without waste of material, the converging of the short prongs holds the plate more socurely and the heel plate is easily, quickly and firmly secured to a heel without the use of special tools.

Having thus described my invention I claim as new 1. A stamped heel plate having a rounded outer end and two converging side arms, a long pointed central prong at the base of the side arms and at right angles to the plate and a short pointed prong on the end of each side arm and at right angles to the arm, the pointed ends of the short end prongs converging.

:2. A heel plate stamped from knife edge bar metal and having a semi-circular outer edge and two converging side arms, a long pointed central prong bent at right angles at the base of the side arms and a short pointed end prong on the end of each side arm and bent at right angles thereto, the pointed ends of the short end prongs converging.

3. A heel plate stamped from knife edge bar metal and having a semi-circular outer end, two converging side arms, each side arm being curved on its outer edge and straight on its inner edge, a long pointed central prong bent at right angles at the base of the side arms, and a short pointed end prong on the end of each side arm and bent at right angles thereto, the pointed ends of the short end prongs converging.

4. A heel plate stamped from knife edge bar metal and having a semi-circular outer end, tWo converging side arms, each converging side arm having a curved outer right angles to the converging side arms,

the pointed ends of the short end prongs converging.

A heel plate having a flat body portion and tWo converging side arms, a long pointed central prong at the base of the side arms and at right angles to the plate, and a short pointed prong on the end of each side arm and at right angles to the arm, the base of the side arms and the base otthe long central prong being in juxtaposltion.

In testimony whereof, I have signed my name to this specification in the presence of tWo subscribing Witnesses.
